The shoe sole structure contains a first protective container, a first elastic pad, a second protective container and a second protective container. The first protective container has a first side having a first containing space and a second side having plural first gutters thereon. The first elastic pad is united with the first side within the first containing space. The second protective container has a third side having a second containing space and a forth side having plural second gutters thereon. The second elastic pad is united with the third side within the second containing space. The second side is united with the forth side. Accordingly the first and second elastic pads are protected from exposing to sunlight and air directly and the first gutters combined with the second gutters form plural channels that greatly increase the elasticity of the shoe sole structure.

TECHNICAL FIELD

[0001] This invention relates generally to a shoe sole structure for footwear. More particularly, the present invention relates to a shoe sole structure that not only provides a shock absorbing effect but also can protect the elastic portion of the shoe sole structure from aging and wear.

BACKGROUND OF THE INVENTION

[0002] Shoes, especially for jogging, running or other sport purposes, have two basic requirements. The principal task of the shoe is to help the act of running, so that the runner moves forwardly as sparingly as possible. The other task of the shoe is to protect the feet for running exertion, so that conditions for the runner's optimum performance may also be preserved or maintained through the latter part of a running race. In addition, in a consumer's point of view, longer life of a shoe sole structure is preferred. To achieve the aforementioned functions, many different shoes have been developed

[0003] Resilience of the sole can be obtained in many different ways. For example, a traditional shoe sole structure is composed of a foaming material for providing elasticity and a rubber layer combined with the foaming material for protecting the foaming material. However the rubber layer can only protect the bottom portion of the foaming material. The surroundings of the foaming are not protected. Therefore the foaming material exposes to sunlight and moisture directly. That causes the foaming material aged and worn quickly. Besides, for the purpose of running or other sports with heavy duties, the elasticity provided by the foaming material of the traditional shoe sole structure is not enough.

[0004] Another design of traditional shoe sole structure is an air cushion structure. However, the cost of air cushion shoe sole is high and the procedure of manufacturing is complex. In addition, sometimes unnecessary deformations take place in the shoe sole of air cushion structure. Accordingly a shoe sole structure with sufficient and proper elasticity as well as long life and comparatively low cost of manufacture is needed.

SUMMARY OF INVENTION

[0005] It is therefore an objective of the present invention to provide a shoe sole structure with sufficient and proper elasticity.

[0006] A further important object of the present invention is to provide a shoe sole structure that can prevent the elastic portion of the sole from aging and wear.

[0007] The present invention, briefly summarized, in one embodiment discloses a shoe sole structure. The shoe sole structure contains a first protective container, a first elastic pad, a second protective container and a second protective container. The first protective container has a first side having a first containing space and a second side having plural first gutters thereon. The first elastic pad is united with the first side within the first containing space. The second protective container has a third side having a second containing space and a forth side having plural second gutters thereon. The second elastic pad is united with the third side within the second containing space. The second side is united with the forth side. Another embodiment of the present invention discloses a shoe sole stricture containing a protective container, an elastic pad and an outsole. The protective container has a first side having a containing space and a second side having plural gutters thereon. The elastic pad is united with the first side within the containing space. The outsole is united with the second side of the protective container.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0023] With reference to FIG. 1 to FIG. 5, The shoe sole structure mainly contains a first protective container 11, a first elastic pad 1, a second protective container 21 and a second elastic pad 2. The first protective container 11 has a first side 14 having a first containing space 110 and a second side 15 having plural first gutters 12 thereon. A pattern layer 112 is united with the first side 14 of the first protective container 11. The first and second elastic pads are made of a foaming material. The first and second protective containers are made of a transparent, waterproof and wear resisting material. The first elastic pad 1 is united with the pattern layer 112 within the first containing space 110. Accordingly, one side and the surroundings of the first elastic pad 1 are wrapped by the first protective container 11. As the application shown in FIG. 1, another side of the elastic pad 1 is united with an insole of the shoe. Therefore the elastic pad 1 is protected from exposing to sunlight and air directly.

[0024] The second protective container 21 contains a third side 25 having a second containing space 210 and a forth side 26 having plural second gutters 22 thereon. A pattern layer 212 is united with the third side of the second protective container 21. The second elastic pad 2 is united with the pattern layer 212 within the second containing space 210. Accordingly, one side and the surroundings of the second elastic pad 2 are wrapped by the second protective container 21. Similarly, as the application shown in FIG. 1, another side of the elastic pad 2 is united with an outsole 23 of the shoe. Therefore the elastic pad 2 is protected from exposing to sunlight and air directly.

[0025] The pattern layers 112, 212 have patterns thereon. The pattern layer 112, 212 can be any color. The second side 15 is united with the forth side 26. The plural first gutters 12 and the plural second gutters 22 are united correspondingly. The shapes of the plural first gutters 12 and the plural second gutters 22 are semicylindrical. Therefore the plural first gutters 12 and the plural second gutters 22 form plural circular channels 16. The formation of the channels can greatly increase the elasticity of the shoe sole structure.

[0026] With reference to FIG. 6, in the embodiment, the shapes of the channels 16 a made by combination of the first gutter 12 a and second gutter 22 a are square. The shapes of the channels can be designed to any shape desired.

[0027] With reference to FIG. 7, in the embodiment, the gutters 12 b, 22 b are close ended. One advantage of the embodiment is that stone or sand will not enter into the channels.

[0028] With reference to FIG. 8, the embodiment contains a protective container 11 c, an elastic pad 1 c and an outsole 24. The protective container 11 c has a first side 14 c having a containing space 110 c and a second side 15 c having plural gutters 12 c thereon. The elastic pad 1 c is united with the first side 14 c within the containing space 110 c. The outsole 24 is united with the second side 15 c of the protective container 11 c.

[0029] With reference to FIG. 9, the embodiment contains all the elements of the first embodiment described above except there is no pattern layer The first protective container 11 d and the second protective container 21 d directly united with the first elastic pad and the second elastic pad respectively.

[0030] With reference to FIG. 10, the embodiment contains all the elements of the first embodiment described above except there is no pattern layer. The first protective container 11 e and the second protective container 21 e directly united with the first elastic pad and the second elastic pad respectively. In addition, the second side 41, 42 of the protective containers have patterns thereon.

[0031]FIG. 11 shows an embodiment that the first gutters 12 f and the second gutters 22 f are interlaced.

[0032] With reference to FIG. 12, the embodiment shows plural plugs 3 are plugged into the channels formed by the combination of the first gutters 12 and the second gutters 22 for preventing sands or rocks fall into the channels. Each of the plural plugs 3 has a connecting portion 31.

[0033] With reference to FIG. 13, the channels formed by the combination of the first gutters 12 g and second gutters 22 g in this embodiment are placed only at the front portion of the shoe sole structure.

[0034] With reference to FIG. 13, the channels formed by the combination of the first gutters 12 h and second gutters 22 h in this embodiment are placed only at the rear portion of the shoe sole structure.

[0035] One of the method of making the shoe sole structure contains: placing protective containers and pattern layers in a mold; heating them to the degree of deformable; vacuating one side of the protective container to form containing space at the opposite side and plural gutters at the same side of vacuating; placing foaming material in the containing space; heating and press the foaming material inside the containing space to fixed shape; and finally combing two sets of the products made as described above by high frequency wave.
